5 Claims.

This invention relates to the art of concrete reenforcing means, and has reference more particularly to reenforcing systems adapted for use in connection with structural beams which consist of a body of concrete or cement having enibedcled therein a steel structural element such as an I-beam, channel beam or the like. In such structural beams it is quite common to associate with the steel structural element a system of wire reenforcement which is also embedded in the concrete and serves to give proper support to the edges and corners of the concrete covering.

The wire reenforcment of the present invention has been designed more particularly for use in structural concrete or cement beams wherein the embedded steel structural element consists of a channel beam set edgewise upright with its web vertical. Among the objects of the invention are, to provide a wire reenforcement well adapted for cooperation with a channel beam to afford the desired bonding of the concrete in the soifit region of the finished beam, to provide a wire reenforcement which, when applied to the channel beam, is securely attached thereto against accidental displacement under the tamping and puddling of the concrete, to provide a wire reenforcement for use in association with a channel beam reenforcing member of such a construction that the several parts of the wire reenforcement will all be held in correct position in the concrete, and to provide a Wire reenforcement for concrete beams that will be of simple construction, economical to manufacture, and easy to apply.

An illustrative embodiment of the invention is presented in the accompanying drawing, wherein: Y

Fig.,1 is a cross-section through a form or mold and a channel beam reenforcement, showing my improved wire reenforcement applied to the beam.

Fig. 2 is an elevation of the longitudinal reenforcing rods and a plurality of wire cups mounted thereon as the clips appear before application of the reenforcement to the channel beam.

Figv 3 is a perspective view of the longitudinal reenforcing rods and a single clip mounted thereon.

Referring to the drawing, l 9 designates a wooden form or mold in which the concrete beam is cast, and ll designates a structural member, herein shown as a channel beam, around which the concrete is cast.

I2 designates each of a pair of reenforcing rods or wires which extend lengthwise of the outer side of the channel beam H and are spaced therefrom by portions of the clips hereinafter described.

53 designates as an entirety each of a plurality of Wire clips which are disposed at uniformly spaced intervals crosswise of the reenforcing rods i2 and are spot welded or otherwise secured to the latter. Each of these clips comprises a substantially vertical limb l4 lying opposite the outer side of the web of the channel beam, a terminal hook l5 that is continuous with the upper end of the vertical limb l4 and is engaged with the top flange of the channel beam in the manner shown in Fig. l, a sofiit reenforcing loop 16 that is continuous with the lower end of the vertical limb it and underlies the channel beam, a hook I! that is continuous with the other end of the loop [6 and is engaged with the bottom flange of the channel beam as shown in Fig. 1, a tie wire l8 which is soldered to and connects the upper end portions of the loop l6 and lies beneath and in contact with the bottom flange of the channel beam, and a spacing finger H], which is soldered to the vertical limb I4 and at its free end abuts against the outer side of the web of the channel beam. This spacing finger l9 and the tie member 3 are preferably formed as parts of a single length of wire, having a connecting vertical portion 20 that is soldered, spot Welded, or otherwise attached to the vertical limb It.

The clip as made and before application to the channel beam has the form illustrated in Fig. 3, wherein the hooks l5 and H are vertical continuations of the members M and It for convenience in applying the clips to the channel beam from beneath the latter. As they are thus applied, after the tie member l8 has come into contact with the lower edge of the channel beam, the portions forming the hooks l5 and H are bent down and interlocked with the top and bottom flanges of the channel beam.

The described construction not only maintains the soffit reenforcement IS in correct position relatively to the channel beam and the external surfaces of the molded beam, but the rods or wires l2 and the vertical limbs l4 also provide a bonding reenforcement for the concrete on the outer side of the channel beam.

Modifications of the described structure may the appended edgewise upright channel beam and comprising a plurality of spaced reenforcing rods extending lengthwise of and opposite the outer side of the web of said beam, and a plurality of spaced parallel chips disposed crosswise of said rods, each of said clips having a substantially vertical limb lying opposite the outer side of said web, a terminal hook continuous with the upper end of said vertical limb engaged with the top flange of said beam, a soffit reenforcing loop continuous with the lower end of said vertical limb and underlying said beam, a hook continuous with said loop en-' gaged with the bottom flange of said beam, and a tie member connecting the upper end portions of said loop and lying beneath and in contact with said bottom flange.

2. A concrete reenforcement of the class described adapted to be mounted on an embedded edgewise upright channel beam and comprising a plurality of spaced reenforcing rods extending lengthwise of and opposite the outer side of the web of said beam, and a plurality of spaced parallel clips disposed crosswise of said rods, each of said clips having a substantially vertical limb lying opposite the outer side of said web, a terminal hook continuous with the upper end of said vertical limb engaged with the top flange of said beam, a soffit reenforcing loop continuous with the lower end of said vertical limb and underlying said beam, a hook continuous with said loop engaged with the bottom flange of said beam, a tie wire connecting the upper end portions of said loop and lying beneath and in contact with said bottom flange, and a spacing finger attached to said vertical limb and at its free end abutting against the outer side of said web.

3. A concrete reenforcement of the class described adapted to be mounted on an embedded structural member and comprising a reenforcing rod extending lengthwise of said structural member, and a plurality of spaced clips secured to and crosswise of said rod, each of said clips having parts engaged with the top and bottom portions of said structural member, parts located opposite to but out of contact with the bottom and a side of said structural member, and parts contacting with said bottom and side of the structural member and spacing said second named parts from said bottom and side.

4. A concrete reenforcement of the class described adapted to be mounted on an embedded edgewise upright channel beam and comprising a plurality of spaced reenforcing rods extending lengthwise of and opposite the web of said beam, and a plurality of spaced clips secured to and crosswise of said rods, each of said clips having parts engaged with the top and bottom flanges of said beam, parts located opposite to but out of contact with the bottom flange and web of said beam, and parts contacting with said bottom flange and web and spacing said second named parts from said bottom flange and web.

5. A concrete reenforcement of the class described adapted to be mounted on an embedded edgewise upright channel beam and comprising a plurality of spaced reenforcing rods extending lengthwise of and-opposite the outer side of the web of said beam, and aplurality of spaced parallel clips secured to and crosswise of said rods, each of said clips having terminal hooks engaged with the top and bottom flanges of said beam, members located opposite to but out of contact with the bottom flange and web of said beam, and intermediate members contacting with said bottom flange and web and spacing said first named members from said bottom flange and web.
